Be it known that I, JOSIAH P. EDWARDS, a citizen of the United States, residing at Shir-- ley, in the county of Hancock and State of Indiana, have invented certain new and useful Improvements in Stock-Watering Tanks,

' The object of my invention is to produce a drinking water may be automatically delivered to stock, the construction being such as to prevent overflow of the drinking'basin when the tank is exposed to the sun.

The accompanying drawings illustrate my invention.

Figure 1 is a central vertical section covf erin an embodiment thereof. Fig. 2 is a simi ar section ona smaller scale of a modified In the drawings, 10 indicates a suitable reservoir, to the lower side of which is conmnnicates with the interior of the reservoir .10 at a point near its bottom throughan opening 12. The upper end of the reservoir 10 is closed by a head 13, which is preferably funnel-shaped to communicate with a pipe 14, which runs downward through the reservoir and communicates at its lower end with an ex ansion-chamber 15, as indicated b the sum opening 14, near the top of the lnthe form shown in Fig. 1 the expansionchamber 15 is of less diameter than the interior of the tank 10, and there is free communication between the interior of the tank and the expansion chamber throdg'h an opening 16, formed through the wall of chamber 15 near its bottom.

In the form shown in Fig. 2the expansion chamber 15 is formed b means of a crosspartition 17, which divi' es the tank 10 into upper and lower compartments. Communication is had from the up or compartment to the expansion-chamber by means of a pipe 18, which passes through the partition 17 and downward some distance into the expension-chamber Arranged within the tank 10 is an air-Vent passage 20, the upper end of which communicates with the hiterior of the tank nearits vent further ingress oi top and the lower end of which communicates with an openinp '21, which leads intoithc dclivery-reccptacle 11 a! a point some distance above the opening 12, but some distance below the top of the delivery-receptor-lc.

The air-vent passage may be placed outside the tank, so as to enter it near the top, or may be entirely omitted. When omitted, a capped vent 30 should be provided.

The operation is as follows; in order to iill the tank, the opening 12 is plugged by any suitable means. Water-is then poured into the cupped cap 13 and ilovrs downward through passage 14 into the expansion-chamber 15 and from thence out and up into the tank 10, the air in the upper part of the tank passing downward through the vent-passage 20. So long as the opening 12 remains plugged the expension-chamber 15 will remain filled with water; but when said opening 12 is unplugged water will low out into the delivery-rcceptacle ll until itriscs high enough to close the opening 21 and thus preair into the to oi' tank 10. Thcreupon by reason of the lact that the water within the expansion-chamber 15 is in direct communication with the external air through tube 14 the water in the cxpansion-chamber will drop in level, so as to be practically on a level with the water in the deiivery-receptacle 11, the top oi the expansion-chamber 15 being higher than the opening 21. if now the entire apparatus be subjected to the heat of the sun, the imprisoned air in the top of tank 10 will expand, thus forcing the water therein downward. The expansion-chamber 15, however, being of an area nearly or quite as large as the area of the tank will permit the water displaced by this expansion, to rise in the expansion-chamber, so that the consequent rise in the delivery-' receptacle 11 will be comparatively small. if, on the other hand, there i ere no expansion-ehainber 15, the displaced. water would rise in the tube 14 and, also in the deliveryreeeptaeie 11; but the tube 14- being of coinparatively small cross-section would not be able to accommodate a material part of the displaced water, and consequently the water would flow out into the delivery-receptaoie 11 and overflow therefrom. The expansionchamber 15 is an. enlargement of the lower such form es to produce s maximum expansion-chember with e minimum diminution of the interior of the tank 10.

I elaim es'rny invention- 1. In a device of the elsss described, a.

closed reservoir heving upperend lower coinpo-tments sepersted by a transverse pertition having sneperture, e drinking-trough connected to said reservoir, a discharge from the lower of said compartments into said drinking-trough and disposed below the upor t per line hessine, and en equslizingpipe lend. g troin the lower of said compartments and tor orienting abo ve the upper of said eo1npertments.

2. in. it device of the class described, a closed reservoir having the cover member spaced below the upper rim and provided with an aperture ooinniuniesting with the interior of the some, :1 detachable closure to.

seid aperture, a. transverse partition dividing the interior of said reservoir into two eo1npiirtnients end having e.eoinpsrtmerit-row heating aperture, :1 (.llillh ing-trough connect ed to ssid'reservoir, ediseharge from the lower of said com ertments into said drinhinge trough and isposed below the upper line ol the same, and on equalizing-pipe extending through said partition and througlissid cover member.

3. in it device of the class described, a. tank having a. hooded upper end, and ii deliveryreceptecle communicating with the interior of said tank near its lower'eiid, of 1: compare tively large expansion-changer arranged in the lower end of said tanlr and communicating with the interior andexterior of the tank.

4-. In a device of the elassdescribed, a. tank having a heeded upper end, and a deliveryreeepteele communicating with the interior of said tank near its lower end, of a compari'r.

tively large expansion-chamber arranged in the lower end of said tank and commun eating with the interior of the tank and eornmuniesting with the exterior of the tank by a passage the upper end of which extends above- {)iLUSlOIkCllflIIIbGI of comparatively large cubic contents arranged in the lower end ol send communicating with the interionpf tank and the tank. in Witness whereof I have hereunto set my hand and seal at Indianapolis, Indiana, this 27tl1dsy of December, A. D. 1905.
